Rkvst for AI agents

DataTrails (formerly RKVST) is an evidence management platform that logs a verifiable chain of custody for supply chain and compliance data. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

What agents do in Rkvst.

01

Look up an asset's history

List events for an asset to see its full chain of custody before making a claim about it.

02

Download supporting evidence

Download an event's attachment to include as proof in an audit or compliance report.

03

Confirm before promoting a member

Get a member's tenancy details first, then promote them only after the access change is approved.

02 · ACTIONS

24 Rkvst actions, graded by risk.

Every Rkvst action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

03 · HOW IT WORKS

Rkvst in three steps.

  1. 01Your users connect RkvstThey add their Rkvst api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, and writes like “update App Registration” can wait for the user to approve.
  3. 03Any agent can actYour agent calls Rkvst through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('rkvst', {
  read: 'allow',
  write: 'ask',        // update_app_registration
  destructive: 'deny',  
})

# Claude Code: the same connection, one URL
$ claude mcp add --transport http arc0 \

04 · AUTH AND DATA

How Rkvst connects.

Users add their Rkvst api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Rkvst connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Rkvst and Arc0, answered.

Q01

Can I use Rkvst with Claude, ChatGPT or Cursor?

Yes. Connect Rkvst to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Rkvst actions you allow.

Q02

How do users connect Rkvst?

Users add their Rkvst api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Rkvst actions can my agent take?

24 in total: 22 read, 2 write and 0 destructive, such as “update App Registration”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Rkvst?

Yes. Allow read actions and deny writes in the Rkvst policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call Rkvst too?

Yes. The same Rkvst connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
